      This is over-generalizing of course but:
      Carbon is not the problem. Almost all of life relies on forms of carbon/oxygen combustion for energy - even us. The problem is the  carbon dioxide that is emited by the combustion process. 98% of atmospheric oxygen comes from the magic of photosynthesis. Both from green plants and oceanic phytoplankton.
      I used to work in this program for several years. Part of a global network monitoring the atmosphere and water.
      Carbon dioxide is considered a major greenhouse gas that traps heat in the lower levels and is a possible contributor to global warming and weather changes. Photosynthesis absorbs CO2 and emits oxygen as a byproduct. Easy to see it is a natural cycle for life as we know it on earth. Restricting the free release of CO2 into the atmosphere would seem to me to be a worthy goal. As is planting more trees and using them more efficientely. Something every individual can partake in to some degree.
      Tree plantations are not the entire answer. A forest needs biodiveristy, and selective harvesting, otherwise one bug or disease can wipe out the entire plantation.
      One day we will all be carbon again and Ma Nature will carry on with or without us:-)

      In these parts here High Carbon refers to high-carbon-dioxide producing/releasing processes, incl. manufacturing, propulsion and heating. The lingo

        In these parts here 'High Carbon' refers to high-carbon-dioxide producing/releasing processes, incl. manufacturing, propulsion and heating.  The lingo short-cut may be confusing to some but I took it to be more widespread. 

        Ergo, 'Least-Carbon' approaches in boats are the least fossil-energy-intensive, both in propulsion but also construction and non-renewable materials-consumption, as those typically depend on a lengthy trail of energy-usage and thus often CO2 release, such as with 100% 'man-made'/heavily-processed materials such as steel, alu, fiberglass, unobtanium, etc.  Hence, the preference for domestically- if not regionally-sourced plywood...
